Design and application of mechanized matched production line in large diameter kilometer vertical shaft construction

Mechanized construction line is the key factor to accelerate construction of vertical shaft. This paper introduces typical domestic construction techniques and mechanized matched production line of large-diameter kilometer vertical shaft construction. During frozen wellbore construction stage, The entreprise equipped with excavators, the center grab rotary, high-capacity upgrade of waste 4.0m³ bucket, concrete hopper bucket and hydraulic decentralized sliding template, high-power winch and other large equipment, and used electric detonators and new technology to reduce blasting vibration; when arriving at bedrock site, additionally reservation of the center grab rotary machine in frozen stage, it increased the new umbrella drilling YGZ-70 heavy-duty rock drill, the effective height of 4.5m metal blade angle of down building templates, the controlled blasting detonators of water resistant, and anti-millisecond electromagnetic stray current technologies etc; At 1038m depth, the shaft changed the twist and used big winch of 4.0m diameter reel. Application shows that shaft mechanized production line meets the needs of ultra-1000 meters vertical shaft construction.
